Abstract:
In an integrated circuit having a first circuit part and at least one second circuit part, which is assigned to a specific functionality of the first circuit part, on one and the same silicon wafer, of which the first circuit part and the at least one circuit part are arranged in non-overlapping, mutually separate regions of the silicon wafer and are connected to one another via connecting elements or lines, during the fabrication, for each exposure plane, with the exception of the exposure plane used for the fabrication of the connecting elements or lines, use is made in each case of a first exposure mask intended for the first circuit part and a second exposure mask intended for the second circuit part. These first and second exposure masks may be arranged on a common reticle for a respective exposure plane.
Abstract:
The invention concerns a high coulomb transfer switch useful for high current pulse supplies, employing a self-bouncing arc mechanism, wherein two cylindrical electrodes are coaxially arranged and the pathway of current inside the switch is specially designed such that arc current sheet positioned between the coaxially arranged electrodes makes a self bouncing movement in an axial and/or circumferential direction. The self-bouncing arc switch according to the present invention makes it possible to maximize the working area of the electrodes, thereby spread arc energy effectively over the electrodes.
Abstract:
A system and method for supporting and providing electrical power to devices. One embodiment includes an elongated member coupled to the structure and configured to support a device and to supply electrical power to the device. A coupling member is operable to engage the elongated member or power bus and support the device. The coupling member is operable to be moved from a first position to a second position along the elongated member to reposition the device with respect to the structure. In one embodiment, the elongated member is configured to supply electrical power to the device substantially continuously during movement of the coupling member along the elongated member.
Abstract:
Resettable circuit interrupting devices, such as GFCI devices, that include a reset lock-out mechanism are provided. The reset lock-out mechanism prevents the resetting of electrical connections between input and output conductors if the circuit interrupting mechanism used to break the connection is non-operational or if an open neutral condition exists.
Abstract:
A circuit breaker (10, 12) includes a sensing circuit (48, 50, 52), a control circuit (46), an actuator (42), an operating mechanism, and an interlock mechanism (70, 94). The sensing circuit (48, 50, 52) is configured to generate the sense signal representative of a power signal flowing through a power circuit (54, 56, 58). The control circuit (46) has a frame (74, 76) and is configured to receive the sense signal and to provide a trip signal on a first terminal (68). The actuator (42) is external to the control circuit frame (74, 76) and has a second terminal (98) coupleable to the first terminal (68). The actuator (42) is configured to receive the trip signal on the second terminal (98). The operating mechanism is coupled to the actuator (42) and is configured to open and close the power circuit in response to actuation of a lever (36). The actuator (42) is configured to actuate the lever (36), in response to the trip signal. The interlock mechanism (70, 94) is coupled to at least one of the actuator (42) and the operating mechanism and is configured to actuate the lever (36) when the first terminal (68) is not coupled to the second terminal (98).
Abstract:
An improved test button assembly for use in a circuit breaker includes a frame and a button member, with the button member being pivotably mounted on the frame. A pair of microswitches are mounted on a printed circuit board that is disposed on the frame. The button member is alternately engageable with the two microswitches, with one of the microswitches being connectable with a ground fault protection circuit, and the other microswitch being connectable with an arc fault protection circuit. In an alternate embodiment, a common electrical contact is mounted on the button member, and a pair of contacts are mounted on the frame, with the common contact being alternately engageable with each of the contacts mounted on the frame. The contacts mounted on the frame are connected with the ground fault and arc fault protection circuits.
Abstract:
Based upon the results of an ID check with an ignition knob lock device which prevents rotational operation of an ignition knob which is used when stating an engine of a vehicle, and of an ID check with a portable unit, a passive control unit transmits to the ignition knob lock device a command to release prohibition of rotational operation of the ignition knob, and performs an ID check with the ignition knob lock device before detecting an operation of pushing in the ignition knob.
